Description

Technical Field

[0002] Modified asphalt refers to asphalt obtained by deep processing of coal tar or ordinary coal tar. During the production process, it needs to be used in conjunction with a reactor and a heating furnace.

[0003] After searching, the patent number CN214270761U discloses a tubular furnace heating method modified asphalt production system. This production system adds a cleaning function on the basis of the conventional tubular furnace heating method modified asphalt production system. By adding a tar intermediate tank and supporting pipelines, using tar as the cleaning medium, and cleverly utilizing the asphalt circulation pump in the original process, all asphalt equipment and pipelines in the production system are thoroughly cleaned, thereby avoiding all hidden dangers of difficulty in resuming work due to blockage of equipment or pipelines.

Since the tar is mixed with debris during the cleaning process, there are many impurities in the tar after use. Direct reuse without filtering can easily lead to reduced tar cleaning effect, and still cause blockage inside the equipment and affect the production of modified asphalt. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] The utility model embodiment discloses a system for producing modified asphalt by a tubular furnace heating method.

[0030] Example 1

[0031] The utility model provides Figure 1-4A tubular furnace heating method modified asphalt production system shown includes a support frame 1 and a reactor 2 fixedly arranged inside the support frame 1, a tubular furnace 3 is fixedly arranged on the top of the support frame 1, the tubular furnace 3 and the reactor 2 are connected, a tar tank 5 is fixedly arranged on the bottom of the upper end of the support frame 1 through a plurality of connecting rods 4, a liquid inlet pipe 6 and a liquid outlet pipe 7 are connected between the tar tank 5 and the reactor 2, the liquid outlet pipe 7 is a corrugated pipe, and the pipe walls of the liquid inlet pipe 6 and the liquid outlet pipe 7 are fixedly sleeved with a liquid suction pump 8, a partition 9 is fixedly arranged on the middle end of the inner wall of the tar tank 5, filter screens 10 are arranged on both sides of the partition 9, and positioning grooves are opened on both sides of the partition 9, and the positioning grooves are plugged into and matched with the filter screen 10.

[0032] During the production of modified asphalt, the preparation work can be completed through the cooperation of the reactor 2 and the tubular furnace 3. After the asphalt preparation is completed, the lower suction pump 8 can be opened to allow the tar in the tar tank 5 to enter the reactor 2. The tar is then circulated inside the reactor 2 and the tubular furnace 3, and the impurities remaining in the equipment are cleaned. Then the upper suction pump 8 is started to suck the tar after the cleaning work from the reactor 2 and push it into the tar tank 5 through the liquid outlet pipe 7. During the tar pushing process, the tar is filtered through the filter screen 10 and accumulated and stored at the lower end of the tar tank 5. Due to the setting of the partition 9, the two filter screens 10 can be used separately to ensure that the tar filtering work can be carried out continuously during the disassembly and maintenance of the filter screen 10.

[0033] Example 2

[0034] Embodiment 2 is based on embodiment 1 in order to enable the filter screen 10 to be quickly disassembled and assembled. Figure 1 and Figure 3 As shown, an installation positioning mechanism is provided between the filter screen 10 and the outer wall of the tar tank 5, and the installation positioning mechanism includes a cover plate 13. A mounting hole is provided on the side wall of the tar tank 5, and the filter screen 10 is slidably arranged in the mounting hole. The cover plate 13 is fixedly connected to the filter screen 10 and covers the outer side of the mounting hole. Moving holes are provided at both ends of the inner part of the cover plate 13, and a card plate 14 is slidably provided in the moving hole. Slide grooves are provided on both sides of the inner wall of the moving hole, and guide blocks 16 are slidably penetrated in two adjacent slide grooves. The guide blocks 16 are fixedly arranged in the card plate 14, and a spring 15 is fixedly provided between the card plate 14 and the inner wall of the moving hole. A card slot for matching the card plate 14 is provided on the outer wall of the tar tank 5, and the card plate 14 is an L-shaped card plate.

[0035] When the filter 10 needs to be replaced after being used for a long time, the two clamping plates 14 on one side of the filter 10 to be replaced are pressed, so that the two clamping plates 14 are close to each other in the sliding fit of the guide block 16 and the slide groove, and the spring 15 is squeezed. At this time, the two clamping plates 14 are pulled out from the inside of the clamping groove, and then the cover plate 13 can be directly pulled to remove the filter 10 from the mounting hole and the positioning groove. At this time, the filter 10 is away from the tar tank 5 and can be replaced.

[0036] Example 3

[0037] Embodiment 3 is based on Embodiment 1-2, and the filtering work of tar can be divided into different areas, and the outlet position of the outlet pipe 7 is adjusted and fixed, such as Figure 2 and Figure 4 As shown, a guide groove 11 is provided at the upper end of the back side of the tar tank 5, and one end of the liquid outlet pipe 7 away from the reactor 2 is slidably arranged in the guide groove 11, and two baffles 12 are fixedly sleeved on the outer side, and the two baffles 12 are respectively arranged on the inner and outer sides of the tar tank 5, and two symmetrically arranged fixed plates 17 are fixedly provided on the back side of the tar tank 5, and a screw rod 18 is rotatably provided between the two fixed plates 17, and a slider 19 is threadedly sleeved on the rod wall of the screw rod 18, and a connecting plate 21 is fixedly provided on the top of the slider 19 through a telescopic rod 20, and the connecting plate 21 is fixedly connected to the baffle 12, and the end of the screw rod 18 passes through the fixed plate 17 and is fixedly provided with a rotating crank 22.

[0038] Due to the snap-fitting cooperation between the two baffles 12 and the guide groove 11, the pipe mouth of the liquid outlet pipe 7 can slide in the guide groove 11, so that when the filter screen 10 on one side is replaced, the crank handle 22 can be driven to rotate, and the screw rod 18 rotates at this time, and drives the slider 19 to move laterally. Under the sliding cooperation between the guide groove 11 and the liquid outlet pipe 7, the liquid outlet pipe 7 moves laterally under the support of the connecting plate 21 and the telescopic rod 20, and moves to the top of the filter screen 10 on the other side. At this time, under the limitation of the partition 9, the tar flowing out of the liquid outlet pipe 7 can contact the filter screen 10 on the other side and complete the filtering work, ensuring that the tar filtering work is carried out while the filter screen 10 can be disassembled and replaced, thereby improving the use effect of the equipment.
